l Application vflied January 11s, i922. serial-'Netware My invention relates to that type of thread-inserting mechanism wherein the material receiving the thread may be hunched upon a needle carrying such thread; such needle being 'of considerable length and .adapted to receive in -bunched condition a considerable amountk of material. The thread employed may serve the function of `securing together the lapped ends of-li-ndependent sections of material, -or suchl` thread, or a plurality of threads may provide a `form of ornamentationv uponI a fabric,with out reference to the joining-'of independent sections of material.

One object of my invention is'tomaterie .ally facilitate the operation of inserting the thread, whether employed for its ornament-al character or'for joining 4aplu-nality -of vsections of fabric or other material.

A. further` object of'my invention is to provide aplurality of needles, each carrying a tliread'whereby I can prodi-ice a .plurality of rows .of stitches providing or simulating a type of embroidery stitches.

A Vfurther object of my invention isto provide means whereby the material can be .crimped or creased. to permit entrance lof the needle as the :fabric ispresented thereto, and a still further object of my invention. is to provide means whereby the bunching of such material through which 4the needle has 'been passed can be facilitated; the material piling Vup on the needlecarrying such thread.

Other features Vof my invention will `be 1 Jointed out hereinafter and referred to iii the claims, and mechanism exemplifying my invention and the 'manner of operating the same Vis sufficiently disclosed in the jaccoinpanyiiig'drawings, in which:

Figure l, is a perspective view, illust-:ratiiig the device forming the subiect 'of my invention as 1t may be employed in practicegthe .saine *be-ing mounted upon, adp-i cent to, Vor in proper relation with respect to a suitable table or other support upon which the fabric or sections 'of fabricto be embroidered or connected may be conveiiiently handled. y Y

Fig. 2, is a sectionalelevation of threading mechanism within the scope of my in veiition.

Fig. 3, is a plan view, partly in section, of a portion Iof the structure forming the subject of my invention.

Fig. 4, is va plan view similar -to Figi 3,A illustrating :a f modifiedv arrangement within the scope of my invention, -andf v i i Figs. 5', 6, 72..-and -8, are diagrammatic -views illustrating fabric to which. connecting or ornamental :Stitches havelbeeni-rap-v plied by the use of "my 'thread-inserting mechanism.

In the drawiiigs, l represents'--.a. suitable bracket or support,-which may-be lattached by bolts 2, at .any vconvenient .point to Va ysuitable frame, preferably efsiich a lcharacter .as to lhold suchbracket or -suppontp-in a rigid condition. Hinged at 3, to this bracket support by a, pivot .pin a4, .is ai .mov-

"Carried by itihe bloclr 6, to-which `an .elongated needle?, is

9, from .a suitable supply,'which thread may pass through an lapertuiie 110, in tlhesblock '6,and normally lie alongside the needle.

Carried' by the bracket support 1,.aiifd2ithe -able'plate 5, `disposed above the 'saniesand longitudinally I' thereof. lpivot pin A: of the hinged cenne'cticngis a plate l5, disposed above. the saine, :are toothed members l1 and 12, which may .be Ain the forni of broadffa'cedspur-wheelswand are in effect y,go'ff'ering wheels; such toothed. members -meshing .with each otherso `that power applied try-'one will-effect' .movement lof the other. Y1'ililliilef it ispossibl'e' that Jche power applying ,means heA connected' to either :one n of these .so .called goti'ering wheels, .in the present instancellhave shown vit las applied tow-the .upper member. or wheel l1, and in the present instance-ahandprank 18, is shown as 'they ower applying means.

lIt will-be understooc, ofcourse that. power from a. motor or` a driven pulley may be einn ployed to 4actuate these gotieritng wheels.

As these:` toothed elements imesh, it will be .understood thatpow-er lapplied-.to one will :effectmovement .of tihleiother.anditlie combined action is such that any fabric, whether single ply, to which ornamental stitches are` to he applied, or lapping portions which are to be connected together, will be crimped or gofi'ered by the meshing teeth ,thereby malriiig temporary folds at more or less regular intervals, so thatV as such folds are successively presented to the point of the needle 7 the latter will enter the material and carry ,p

the thread; through such folds. Continued movement of the toothed members forl the Vflanged to guide such chain; the toothed clements-being annularly notched or groovedv at 17 and'18, respectively, to permit' passage of the chain and its teeth. When a single needle is employed, it may be disposed centrally with respect to the toothed elements, audrthe said teeth Will be addi- Y tionallynotched or cut away at19 and 20,

respectively to accomn'iodatesaid needle. If more than one needle is provid-eil, asV indicated inr F ig. et, the teeth will be cut away or notched accordingly, tov accommodate the same. I preferably apply a cover 21, to enclosefthe uneclianism carried by the upper plate 5.

It will be understood, of course, thatJ the vthread applied may be one of a ibrous iiature, cotton, linen, Wool, silk, or the like, and when ornamentalst-itches are being applied, yarn of an ornamental character and relatively thick may be applied. If necessary1 or desirable for any purpose, a wire, or a-v thread made up of -Wirej filaments, can be carried by the needle to be passed either through fabric, orthrougli any similar or suitable material design-ed to be connected together or to be ornamented by the thread applied. 1

In F ig. 5, I have shown the manner in Vwhich tivo sections of fabricl may be connect-k ed together bythe thread-inserting means.

Bags may be sewn in this manner. In Fig.

`i v6, I have shown the manner in which a plura-lity of threads may be applied to provide an ornamental effect. In Fig. 7, I have shown sets of ornamental threads in groups, varying in number, and in F ig. 8, I vhave shown another arrangement ofgrouped threads, all of which may be applied by the means or mechanism forming the subject of my invention.

In this connection, of course, it will be understood that a plurality of needles or sets of needles may Abe set in any desired relation with Yrespect to the toothed members Which etl'ect the crimpingor gotici-ing of the fabrics, so as to properly present it lo the thread carrying` needles.

1. Thread-inserting means, comprising a pair of toothed Wheels, means for moving said wheels; the latter being adapted to engage and goffer a section o f fabricya needle arranged to enter the goffered folds of the fabric at the bite ofgsaid Wheels and carryV tween the same will be given a series of regu-y lar folds; one of said Wheels being mounted in the fixed support and the other in the movable support'liinged thereto, a needle carried by the hinged portion of said movableivheel support; said toothed Wheels being grooved to accommodate said needle, means for moving said Wheels, and additional means for imparting longitudinal movement to the folded fabric after it has left its engagement with the Wheels.

Thread-inserting means comprising a pair of toothed Wheels, means yfor moving said Whe-els in toothed engagementwhereby ar section of fabric caught between the same will be given a series of crimps or folds,a

hinged member supporting one of said Wheels and a fixed member support-ing the other Wheel, a block carried by the hinged portion of said movable supporting member,

a needle carried by said block and arranged to receive thevfolded fabric, means for moving the toothed Wheels, and a toothed chain passing over one of said wheels and serving to impart longitudinal movement to the goffered and threaded fabric and pile the saine up on said needle.

In Witness whereof I have signed this specification.
